It is narrated from Masruq that a man recited Surah Al-Baqarah and Al-Imran in the presence of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him). He said: "You have recited two such Surahs in which is the Greatest Name of Allah; if supplication is made with this Name, it is accepted, and if something is asked, it is granted."
